Rcamuglia: Great shot on the fly there at 50 yards!
Good for you.
I have tried several times to squish a fly with my scope sighted rimfire and centerfire Rifles - at both 50 and 100 yards.
I do NOT think I have ever successfully done so though.
But many years ago (about 55 to be more exact!) I was spotting for my friend who was shooting his then brand new Remington 700 BDL Varmint in caliber 6 m/m Remington with a nifty Redfield 3200 scope in 20 power.
Anyway what we called a "bull-fly" (large fly) came and landed on his target just inches above where his 100 yard group was forming.
Johnny and I saw it at the same time and he says "watch this".
He fired at the fly and it disappeared instantly - but as proof of the hit a drop of blood came oozing down from the bottom of his new 6 m/m bullet hole.
We were gleeful at his feat because back 55 years ago "accuracy" was NOT what it can often be today.
Again good shooting on your part.
Hold into the wind
